The THORNTAIL KeyMod Picatinny Offset Adaptive Light Mount is designed to directly attach SureFires M300s, M600s Mini-Scout and any 1913 rail mounted weaponlights (INFORCE APL, WMLs, Surefire X300s, X400s, Streamlight TLRs) to a KEYMOD Compatible Forend BCM is introducing three new KeyMod mounts for lights: 1913 KeyMod, Scout KeyMod, and One Inch KeyMod.x15. Id like to see a kmr like handguard from BCM in M-lok. Too bad it will never happen. New for 2018, these AR15 .556 handguards have been built to provide rugged, reliable performance.They feature seven panels of KeyMod mount-ability, built-in anti-rotation indexing and proprietary designed Steel mounting hardware to ensure easy rock solid installation.
